Gearbox

i would love to know if the zc33s/31s have this stupid "protection".
the zc32s is an awful car to drive when cold, horrible gearbox feeling, plus this protection.

I would say no, it doesn’t. It’s possible there is some built in control while the engine is in warm up but to the driver it’s not really noticeable, and certainly nothing like the ZC32 was where it holds back until warm.

I can honestly say that the holding back aspect of the ZC32 cold engine doesn't really bother me at all. At the end of the day I personally never try to thrash any car engine until Its warmed up. And let's be honest It doesn't take long before the engine Is at running temperature anyway 🤔

No it’s a few minutes at most before you feel it start to improve. Ultimately you have to trust Suzuki do that for a reason!

After further overthinking, and discussions for the Swift Sport Difficult Gear changing when cold, I am still undecided as which oil to try.

I wont be racing round any track's so mostly normal use up to the rev limit.

Can anyone look at the info below and shed any light on which is most suitable, or important part of the spec?

Kind regards

I wouldn’t have an idea which to use without looking into it, but as a suggestion have you considering enquiring with CTC Performance to see what they recommend?

I haven,t David, and thank you for your reply, however I emailed Redline in America with all the details on my car and they recommended the MTL 75W80 GL4.

I like the idea of the Redline gear oil because it is specifically GL4 and not a mix to cover GL4 & GL5, and there is a lot of good feedback on the internet for it improving gear changes.

I think I am going to go ahead with the MTL 75W80 GL4. If it is not a success I will contact some other people such as CTC and try something else in say six months time.

Info below is from Redline website.

Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
Offers quicker shifts, A perfect synchronizer coefficient of friction
Eliminates notchy shifting, even when cold
Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
Excellent for high- and low-mile transmissions

i 've heard readline is and excellent product, go for it.

Thank you for the reply, I'm using a friend's hydraulic two post lift next Saturday to get it done, hopefully it shows an improvement.

Changed the gear oil today using the MTL 75W80 GL4 and had no problems. The old oil dripped for about twenty minutes, so I used the time to give the underside a good check over including brake discs etc, all looked good. You have to remove a plastic shield to have easy access to the filler plug, and I took the water bottle off its mounting plate up above it for easy use of a filtered funnel and tube to re-fill the oil.

The oil that came out looked very clean, the Redline oil is red in colour and I would say seemed thinner in consistency than what came out.

I drove the car for about ten miles afterwards and it was changing nicely up and down the gears, no resistance from third to second which was the main gripe I had. however weather is quite mild today.

I will report back next Saturday with what I think the result is.
